Engine Lubricant

The main purpose of engine lubricant is to prevent as much metal on metal contact as possible. An engine contains hundreds of moving parts that must be kept separated from each other. If metal surfaces come in contact, wear may occur and friction will increase. With friction comes heat, and heat will warp and distort moving parts. Engine lubricant creates a slick film between metal parts that lets them glide over each other. Engine lubricants are expected to provide the following:
